Which of the following is NOT a function of slicing software?

Slicing software plays a crucial role in the preparation of 3D models for printing by converting them into a language that 3D printers can understand, primarily G-code. The primary functions of slicing software include creating G-code, determining printer movement, and adjusting layer thickness.

Creating G-code is essential because this is the code that dictates the printer's actions, instructing it on how to move and extrude filament. Additionally, slicing software calculates the path that the printer’s nozzle must follow, which is part of determining printer movement. It also allows users to adjust layer thickness, directly influencing print quality and speed.

However, converting 2D images to 3D models is not within the scope of slicing software. This function is typically performed using CAD (Computer-Aided Design) software or 3D modeling software, which enables users to design and create three-dimensional representations of objects. Slicing software assumes that a 3D model has already been created and focuses on preparing that model for the printing process rather than generating it from 2D images. Thus, the function of converting 2D images to 3D models does not fall under the capabilities of slicing software.
